现在先查下migration_one.table_11里有什么：

SELECT * FROM migration_one.`table_11`;

id      name    
------  --------
12321   hehe    
1321    haha

管理员终端打开输入：

D:\start_java\lwsmysql\mysql-8.0.17-winx64\bin\mysqldump.exe -u  root -h 127.0.0.1 -proot  -P3307 migration_one table_11 --where="name like 'h%'" > D:\start_java\XinQiUtilsOrDemo\testMigrationMySQL\table_11_t_d_by_name.sql

得到结果：

执行结果：

如果只想要name以’he’开头的字段数据那么就只需要修改where文本里面的数据：

D:\start_java\lwsmysql\mysql-8.0.17-winx64\bin\mysqldump.exe -u  root -h 127.0.0.1 -proot  -P3307 migration_one table_11 --where="name like 'he%'" > D:\start_java\XinQiUtilsOrDemo\testMigrationMySQL\table_11_t_d_by_name_he.sql

执行结果table_11_t_d_by_name_he.sql：

D:\start_java\XinQiUtilsOrDemo\testMigrationMySQL>D:\start_java\lwsmysql\mysql-8.0.17-winx64\bin\mysqldump.exe -u  root -h 127.0.0.1 -proot  -P3307 migration_one table_11 --where="name like 'he%'" > D:\start_java\XinQiUtilsOrDemo\testMigrationMySQL\table_11_t_d_by_name_he.sql
